This is the common thought among the Lord-level alien shark insects and even the Crown Lord alien shark Lords.
After battling for over fifteen minutes,
when those Leader-level alien shark insects were nearly all dead or injured,
these Lord-level alien shark insects finally began to falter; they started attacking the window glass.
Then, to their shock, during the battle, they found the windows had been fortified to be as solid as the World Barrier.
It was too late for them to escape.
"Boom, boom, boom..."
Three twenty-meter-long Crown Lord alien shark insects swung their heavy tails fiercely against the window glass.
Dark Rune Mysteries were even capable of shattering large pieces of glass debris.
But this "Barrier Glass" with a thickness of forty to fifty meters was not something they could penetrate in a short time.
While they attacked, many powerful fighters also began their assault on these Crown Lord alien shark insects.
